A diver wearing a self-sustaining
back-pack-type mask returns from the depths with a bit of wreckage.
The diver wears heavy gloves to prevent injuries from sharp objects
below, as well as the usual flippers for maneuvering through the
water. The UDT men are called into service whenever there is
underwater work to be done efficiently and promptly, and their
ability to work under all conditions has become a tradition of this
rugged service.
